Silane compound and processes for the preparation thereof |
(57) Novel silane compound, alkoxy cyclopentyl dimethoxysilane, is prepared by reacting
cyclopentyl trihalosilane with ROH and then with methanol, or by reacting cyclopentyl
trimethoxysilane with ROH, wherein alkyl in the alkoxy or R in ROH stands for an organic
group selected from the group consisting of sec-butyl, tert-amyl, cyclopentyl, oxa-3-cyclopentyl,
cyclohexyl and 2-isopropyl-5-methyl cyclohexyl groups. The silane compounds are useful
as a catalytic component for olefin polymerization and as a silane coupling agent.
